Surge protector

SLS-C20/1+1

Lightning and surge arrester for single lines (F+N) 220 V.

Type 2 (Class C) protector, suitable for protection of low voltage lines against lightning strikes and transitory surges of up to 20kA (8/20) in TT (TNS) networks.

Recommended for industrial installations, distribution boards, buildings with low risk of receiving lightning strikes or fed by underground power lines.

Characteristics
  • Single phase protector (1-pole + NPE).
  • Provides high protection and low residual stress, for its combination of high performance varistors and encapsulated spark gap.
  • Easily replaceable plug-in modules with locking system.
  • Base and modules configured for secure mounting.
  • Easy maintenance through local fault locator.
